drm/fb_helper: Create wrappers for fb_sys_read/write funcs
Some drm drivers populate their fb_ops with fb_sys_read/write fb sysfs
ops.
Create a drm_fb_helper function that wraps around these calls.
This is part of an effort to prevent drm drivers from calling fbdev
functions directly, in order to make fbdev emulation a top level drm
option.
v3:
- Fix kerneldoc errors
v2:
- Added kerneldocs
- Follow the drm way of aligning of arguments in func definitions
- Remove unnecessary checks for non NULL fb_info
